A poster has been displayed in a data center that reads. "Anyone caught taking photographs in the data center may be subject to disciplinary action." Which of the following control types has been implemented?
Correct Answer: C
A deterrent control is a type of control that has been implemented by displaying a poster that reads "Anyone caught taking photographs in the data center may be subject to disciplinary action.", as it aims to discourage or prevent unauthorized or malicious activities by warning the potential perpetrators of the consequences or sanctions. The other options are not the correct types of control, as they are more related to the correction, detection, or prevention of unauthorized or malicious activities, respectively, rather than the deterrence of unauthorized or malicious activities.
